Description
This unit covers laying out, manufacturing and finishing precision models.
Notes
Elements and Performance Criteria
1. Determine job requirements
  • 1.1. Drawings, instructions and specifications are interpreted and understood.
  • 1.2. Appropriate material is selected to meet specifications.
2. Layout model
  • 2.1. Finished model design is conceptualised and planned with reference to customer's specifications (written or verbal) for finish, quality and form, using applicable processes.
  • 2.2. Contractions allowances, clearances, tapers etc. are calculated to establish model parameters.
  • 2.3. Datum boards, jigs and fixtures are designed and manufactured as required.
3. Manufacture model
  • 3.1. Sequence of manufacture, including build-up on datum board, establishing datum's mark out of model and areas to be NC/CNC machined, are determined.
  • 3.2. Appropriate machines and machining processes are selected to shape/produce model to specifications.
  • 3.3. A range of hand and hand held power tools is selected and used utilising acceptable techniques and procedures to fashion/manufacture model to fine tolerances according to specifications, ensuring that surface finish is appropriate to the type of model.
  • 3.4. Appropriate measurement/calculations are undertaken to check specifications, including coordinate measuring and machine checking as required.
  • 3.5. Where necessary, all deviations or modifications to original tooling design, prints or plans, are recorded and reported consistent with standard operating procedures.
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Material
Timber, metal, plastic, fibreglass, composites etc.
Processes
High volume foundry tooling, injection moulding, pressure die casting etc.
EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
A person who demonstrates competency in this unit must be able to develop and manufacture precision models. Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with developing and manufacturing precision models or other units requiring the exercise of the skills and knowledge covered by this unit.
Method of assessment
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
